Description

Technical Field

[0001] This utility model relates to the field of cup body processing technology, and in particular to a turntable eccentric pressure compensation structure. Background Technology

[0002] In daily life, insulated cups are commonly used containers that can keep hot water hot for a long time. During the production of insulated cups, the welding process is crucial and frequent, as the welding quality of the cup body and other container products directly affects the appearance and performance of the insulated container. After welding, some weld joints on the cup body are prone to unevenness and discrepancies with the original dimensions. These require roll forming of the weld seam to facilitate subsequent polishing processes, making the weld seam as smooth as the rest of the outer surface of the cup body.

[0003] However, conventional weld roll forming methods have shortcomings, such as easily causing scratches and damage to the product's appearance outside the weld. During the weld roll forming process, the roller applies force from one side, and the uneven force between the roller and the container affects the product's processing quality and efficiency, so improvements are necessary. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a turntable eccentric pressure compensation structure, which can solve the problem that stamped parts are easily stuck in the stamping hole.

[0005] This utility model solves the above-mentioned technical problems through the following technical means:

[0006] An eccentric pressure compensation structure for a turntable includes a chassis, a drive unit, and an eccentric mold. The drive unit is installed inside the chassis. An operating platform is provided on the top surface of the chassis. A first bearing seat and a second bearing seat are mounted on the operating platform. A servo moving module is slidably mounted above the operating platform via a support mechanism. The servo moving module is opposite to the first bearing seat. A rolling roller is driven to the bottom of the servo moving module. A transmission component connects the servo moving module and the first bearing seat. The eccentric mold is mounted on the second bearing seat and is used to clamp a container to be processed. The drive unit drives the rolling roller to roll the container via the transmission component and the servo moving module. The servo moving module also moves the rolling roller closer to or further away from the container for pressure compensation.

[0007] Furthermore, the support mechanism includes a vertical plate and crossbeams. The vertical plate is fixedly installed on the back side of the operating table, and two crossbeams are installed opposite each other at the top of the vertical plate. Slide rails are provided on the opposite surfaces of the two crossbeams, and the servo motion module is slidably installed on the slide rails. A driver is installed on the vertical plate, and a lead screw is connected to the output end of the driver. The lead screw is threadedly connected to the servo motion module to drive the servo motion module to move.

[0008] Furthermore, the servo motion module includes a slider and a gearbox mounted on the slider, the input shaft of the gearbox being connected to the transmission component, and the output shaft of the gearbox being connected to the rolling wheel.

[0009] Furthermore, the transmission component includes a first coupling, a transmission rod, a second coupling, and an adapter. The first coupling is mounted on the first bearing housing and connected to the drive component. The second coupling is connected to the servo motion module through the adapter. The transmission rod is connected between the first coupling and the second coupling.

[0010] Furthermore, both the first and second couplings are cross couplings; the adapter is a universal joint or a ball bearing. Thus, the rotational freedom provided by the first coupling, the second coupling, and the adapter allows the servo motion module to maintain power transmission to the rolling rollers during movement.

[0011] Furthermore, the transmission rod includes a telescopic cylinder and a telescopic rod, the telescopic rod being slidably sleeved inside the telescopic cylinder and extending from the top of the telescopic cylinder.

[0012] Furthermore, the eccentric mold includes a turntable and an eccentric rod. The turntable is mounted on the second bearing seat, the bottom end of the eccentric rod is mounted on the turntable, and the top end of the eccentric rod is provided with an inner support for supporting the container. The inner support can be a bearing mounted on the eccentric rod, and the outer diameter of the bearing is slightly smaller than the inner diameter of the container, so that the container can be fitted onto the eccentric mold.

[0013] Furthermore, the turntable is rotatably mounted on the second bearing seat, and a second drive shaft is connected to the bottom of the turntable, which is connected to the drive component.

[0014] The beneficial effects of this utility model are:

[0015] This application uses a second bearing housing to install the eccentric mold. When rolling the weld seam of the container, the container is first clamped, and the eccentric mold supports the inner bottom of the container. Then, the drive unit is started, and the rolling roller is rotated through the transmission unit and servo moving module. At the same time, the servo moving module is controlled to move closer to the container to roll the container. The position of the rolling roller rolling the weld seam basically corresponds to the support position of the eccentric mold, which avoids scratching damage to the inside of the container. The process is simple and highly efficient, ensuring the accuracy of the container's dimensions and the integrity of its appearance. Attached Figure Description

[0025] Example 1

[0026] like Figures 1 to 4 As shown, this embodiment provides a turntable eccentric pressure compensation structure, including a housing 100, a drive component 112, and an eccentric mold. The drive component 112 is installed inside the housing 100. The drive component 112 includes a servo motor and a transmission pair. The servo motor is installed inside the housing 100 via a mounting strip. The typical transmission pair includes a drive wheel, a transmission belt, and a driven wheel. The drive wheel is installed on the output shaft of the servo motor, and the driven wheel is installed on the top surface of the housing 100 via a first transmission shaft 114. The drive wheel and the driven wheel are connected by a transmission belt, referred to here as the first transmission belt 113. An operating platform 101 is provided on the top surface of the housing 100. A first bearing seat 102 and a second bearing seat 109 are installed on the operating platform 101. A support mechanism 121 (see reference) is provided above the operating platform. Figure 6A servo moving module 106 is slidably mounted, with the servo moving module 106 facing the first bearing seat 102. A rolling roller 107 is driven to the bottom of the servo moving module 106, and a transmission component connects the servo moving module 106 and the first bearing seat 102. An eccentric mold is mounted on a second bearing seat 109 for clamping the container 200 to be processed. The drive component 112 drives the rolling roller 107 to roll the container 200 through the transmission component and the servo moving module 106. During the rolling process of the container 200, the servo moving module 106 can be controlled to move as needed, thereby driving the rolling roller 107 to move closer to or away from the container 200 for pressure compensation. Since the force applied to the container 200 by the rolling roller 107 can be large or small when the servo moving module 106 moves, pressure compensation is achieved. After the container 200 is rolled, the servo moving module 106 can be controlled to move, driving the rolling roller 107 away from the container 200 and out of contact; then the container 200 can be unloaded.

[0027] In this embodiment, as Figure 6 As shown, the support mechanism 121 includes a vertical plate and a horizontal beam, with the vertical plate fixedly installed on the back side of the operating table 101 (to...). Figure 6 For example, on the back side (right side), two crossbeams are installed opposite each other at the top of the vertical plate. The operating platform 101, the vertical plate, and the crossbeams can be installed by welding. Slide rails are provided on the opposite surfaces of the two crossbeams, and the servo motion module 106 is slidably mounted on the slide rails. A driver is installed on the vertical plate, and the output end of the driver is connected to a lead screw, which is threadedly connected to the servo motion module 106 to drive the servo motion module 106 to move. The slide rails provide limiting and guiding functions; the driver can be a conventional motor.

[0028] In fact, the driver can also be a linear motor as needed; the moving part of the linear motor is mounted on the servo moving module 106, and the stator part of the linear motor is laid on the slide rail; the movement of the servo moving module 106 is achieved by driving the linear motor.

[0029] In this embodiment, the servo motion module 106 includes a slider and a gearbox 105 mounted on the slider. The input shaft 115 of the gearbox 105 is connected to a transmission component, and the output shaft 116 of the gearbox 105 is connected to a rolling roller 107. The transmission component includes a first coupling 103, a transmission rod 104, a second coupling 111, and an adapter. The first coupling 103 is mounted on a first bearing seat 102 and connected to the first transmission shaft of the drive component. The second coupling 111 is connected to the input shaft 115 via an adapter, and the transmission rod is connected between the first coupling 103 and the second coupling 111.

[0030] After the servo motor is started, the first transmission shaft 114 and the first coupling 103 are driven to rotate through the transmission pair. The first coupling 103 drives the input shaft 115 to rotate through the transmission rod 104, the second coupling 111, and the adapter, which in turn drives the output shaft 116 to rotate. The rotation of the output shaft 116 drives the rolling roller 107 to rotate, which rolls the container 200.

[0031] During the rolling process of container 200, the slider can be controlled to move under the guidance of the slide rail as needed, thereby driving the rolling roller 107 to move closer to or away from container 200 to compensate for the pressure on container 200. This pressure compensation is achieved by reducing or increasing the pressure according to the actual situation to achieve more precise rolling.

[0032] In practice, to ensure the servo motion module 106 can move while maintaining power transmission, both the first coupling 103 and the second coupling 111 can be selected as cross couplings; additionally, the adapter is a universal joint or a ball bearing 110. When the servo motion module 106 moves, the distance between the first coupling 103 and the second coupling 111 expands, so the transmission rod can be designed to be telescopic. Specifically, in this embodiment, the transmission rod 104 is selected to include a telescopic cylinder and a telescopic rod, with the telescopic rod slidably fitted inside the telescopic cylinder and extending from the top of the cylinder. For example, the telescopic cylinder is fixedly connected to the first coupling 103, and the telescopic rod is fixedly connected to the second coupling 111; the telescopic rod is selected as a square rod or a hexagonal rod, which facilitates power transmission while extending and retracting.

[0033] In fact, the transmission rod 104 can be selected as a hydraulic rod according to the needs of the embodiment.

[0034] In this embodiment, the eccentric mold includes a turntable 108 and an eccentric rod 118. The turntable 108 is mounted on the second bearing seat 109, and the bottom end of the eccentric rod 118 is mounted on the turntable 108 and locked by a locking bolt. The top end of the eccentric rod 118 is provided with an inner support portion 117 for supporting the container 200. The inner support portion 117 can be selected as a bearing or other structure that can provide rotational support. The inner ring of the bearing is fixedly connected to the top end of the eccentric rod 118. The outer ring of the bearing is rotatable and contacts the inner wall of the container 200.

[0035] Example 2

[0036] like Figures 4-6 As shown, in this embodiment, unlike embodiment 1, the turntable 108 is rotatably mounted on the second bearing seat 109, which can be achieved using a deep groove ball bearing. A second drive shaft 119 is connected to the bottom of the turntable 108, and the second drive shaft 119 is connected to the drive member 112. Thus, the drive member 112 can also drive the turntable 108 and the eccentric mold on the turntable 108 to rotate.

[0037] The drive component 112 is a servo motor. A secondary drive wheel is installed on the output shaft of the servo motor, and a secondary driven wheel is installed on the second transmission shaft 119. The secondary driven wheel and the secondary drive wheel are connected by a second transmission belt 120 to realize the transmission of power.

[0038] In fact, on the one hand, the rotation speed of the rolling roller 107 and the turntable 108 can be controlled by adjusting the rotation speed of the servo motor; on the other hand, the rotation speed of the rolling roller 107 and the turntable 108 can be adjusted by pre-selecting the number of teeth or transmission ratio between the driving wheel and the driven wheel, and the number of teeth or transmission ratio between the secondary driven wheel and the secondary driving wheel.

[0039] In this embodiment, the inner support portion 117 of the eccentric mold can be selected as a flexible support ring. Preferably, the flexible support ring can be made of copper, rubber, plastic, etc.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
